Second NSW schoolgirl approached by man

Police investigating the assault of a girl at her Lake Illawarra school believe it could be linked to another incident in the area on the same day.

An 11-year-old girl was allegedly forced into a toilet cubicle at her school on Gloucester Boulevard at 1.20pm on Thursday and tied up.

The man fled, and the girl managed to free herself and tell a teacher what had happened.

Later, a 12-year-old girl walking between classrooms on school grounds in Berkeley was approached by a man who gestured for her to come towards him. She ran back to her classroom and the matter was reported to police.

Officers say the man in that incident was of Caucasian appearance with olive skin and was about 25 years old.
